Options are not automatically exercised. They will be exercised right before expiration in March if your contract is in the money. The only problem with writing a call is that when the stock rises it will be hard to close out your position.
But because the stock goes above 32 when a strike is 32 does not automatically mean you will be assigned and most of time you aren't because it usually happens right before expiration. I would only write a covered call if you are looking for range bound move on the stock between now and March. This means you expect it to be around $32.
You can also adjust your position but if you are long stock and short calls it is kind of hard and it can be a money losing proposition.
