Technically, any day that a salaried employee works at all he or she should be paid his or her daily salary. Generally, responding to mandatory employer emails or texts--i.e. ones you have to respond to--are work, so while it is impossible to say for certain without a more detailed analysis, at first glance it would appear you are owed your salary for any days you "worked" by responding to messages from your supervisor or employer.That said, if  you don't have an employment contract, you are an employee at will, which means you may be fired at any time, for any reason--such as not being a team player. If you press for pay for days that you only worked a few minutes, or perhaps an hour or two, you may find that your employer will pay you, but then terminate you. While you might then be able to bring an action for illegal or improper termination, on the grounds you were retaliated against for a wage claim, it's not clear you would win under these circumstances. Therefore you should think carefully about what is in your interest here--you company apparently tried to accomodate you, so possibly retaining a job with a company which will do this is more important than seeking a few days pay.
