Narrative: Our facility has been back on a normal schedule for around 2 months now but we are operating extremely short staffed due to the amount of people out due to the pandemic.  This is forcing those of us that still come to work to work harder.  I was working GC and LC combined since this is now the 'new normal.'  I commented to the CIC who was also working FD (pre-pandemic we would have had a Supervisor a GC; a FD; and a LC). 'Why did the TMC switch flows when we have a 7 knot tailwind?'  He agreed that it was an early call but this happens a lot and I believe it happens because ZZZ TRACON is still on 5 days on and 5 days off and they don't have the staffing to open positions which is causing ZZZ to operate in a way that I believe introduces more risk.On the west side we normally have three runways but one is closed due to a construction project; and numerous taxiways are closed as well.  In a north flow we are forced to land on Runway XXR when we would normally not do this and the East side keeps all the departures.  This causes the situation that happened to me.  Aircraft X goes around and I issue the standard 340 and climb to 3;000; he went around due to the tailwind.  I then issue instructions on GC to alleviate a conflict there.  I then notice a suppressed data tag of a west bound departure off of the west side (Aircraft Y); and issue Aircraft X a further turn to 270 and coordinated with the departure controller.  The suppressed data tag was a huge factor in me not seeing the east side departure heading west; and the conflict on GC was another distraction.ZZZ TRACON needs to return to a normal schedule so they can staff their final monitor positions.  ZZZ does not need to be departing west bound departures off of the east side when ZZZ1 TRACON is landing XXR; especially when the weather is marginal like it is today.  Additionally; ZZZ TRACON does not need to be landing XXR at all; because that forces us to depart XYL which involves multiple crossing on Runway XXR (more risk).  ZZZ TRACON needs to land the normal arrival runways and if they can't do this due to their staffing then they need to return to a regular schedule.  Most of us here are fed up with what is being asked of us and the safety of the system is quickly eroding to appease the users demands and ZZZ's TRACON staffing.




Synopsis: Controller working Ground and Local combined reported a conflict resulting in an aircraft having to go-around.  Reporter stated Tower does not need to be departing westbound aircraft off the east side of the airport.
