Anecdote... My employer suspended most promotions and merit increases. They also suspended the 401k match. I assume by the time things are back to normal, I'll be out 9-12 months of matching, and will be 18 months without a merit increase. Any longer than that, and I'll be shopping for another position elsewhere. (and they only get that much leeway because it's a nice place to work, I walk to the office in normal times, and simple inertia of a 20 year career there).
