I work on a small team of 3. I am going on vacation at the end of February after my 1 year anniversary with the company, My vacation is approved, paid for, as well as expensive and non refundable. It's been planned since 6 months ago, and I notified my boss and co workers last month, so everybody has had plenty of time.
Both of my coworkers have told me they are planning to quit at the beginning of February, which will leave only me to cover 3 people's jobs. Normally this would be fine and I'd hang in there till they get replacements, but even if we do get replacements in time, they will not be able to cover everything while I am away, which means my boss will revoke my vacation time.
I feel that I am personally getting severely unfair treatment here. I asked if they would give our boss a 1 month notice so that there would be enough time to hire, train and get new people set up, but they both laughed and said no, since they appear to be on a personal mission to hurt the company as much as possible.
They said they chose to quit at this time, since they know the company would be put in a hard position since I would be gone (they said they didn't realize this would simply result in my vacation being revoked).
My dilemma is, their desire to "stick it to the company" is going to seriously affect me in many ways. I'm not particularly close to either of them, but I am torn between upholding my morals, and keeping this to myself, while at the same time covering my own back so I am treated fairly.
What are my options for resolving this situation, including telling my manager?
