Having said that, I think it is right to say that there does seem to be a drive in human beings to find meaning and significance in their work. We do not want to think that work is pointless. It engages us intellectually, emotionally, and volitionally. It calls forth important human capacities, and I think that is what everyone wants to experience, but I do not know if all work is capable of evoking that experience. Indeed, classically understood, the Christian notion of vocation does not require work to evoke that experience.
Vocation can be overdone in a couple of ways.
First, it sometimes places work at the very center of human consciousness in ways that I do not think it has to be. One could find the primary meaning of life in being a father rather than in being a worker. Or one could understand the point of work simply in providing for one's family. The second problem is that the notion of vocation sometimes makes one feel guilty for not finding meaning in tedious and boring work, as if somehow one ought to be more engaged. I do not think that the notion of vocation, which is supposed to energize work, is effective if it simply makes people feel guilty.
