It seems that a lot of the suggested solutions (take time off, be more honest about your emotions, etc.) are necessarily things that are difficult to do for people who are not in management positions. Requesting long blocks of time off or being forthcoming about your emotions are easily things that can be used against you in employee reviews and other similar situations.
In cases of severe burnout, the situation is more dire since people earning a lower salary might simply not be able to step back from work to take a year off, for example (something that was suggested by another poster here).
