You can be an acting anything, pretty much, an Acting Manager, Acting Head, Acting Editor, but your role is recognised. So in my friend's case, the Acting CEO got the job title, the money and the recognition. She was lucky. Sometimes, a company might not find a replacement immediately, or perhaps not find one at all. And some poor person still has to do all the extra work. That person might be acting as the CEO. They're doing the work but not necessarily getting the recognition, the pay or the official job title, they may or may not be. So, two examples. Maurizio is the Acting CEO That means he gets the official title, the money, the recognition. And he's also doing the work. he's acting as the CEO. On the other hand, poor old Maria, in her company, is acting as the CEO but she's not getting the job title or the extra money; she's not officially the Acting CEO. Now a quick word about a related phrasal verb "act up". If you fill an acting position, it's normally a level above your usual job. You're acting up. So, we can say, for instance. Maurizio is acting up while Glenda's away. You have to be careful with this verb though. Like many English phrasal verbs it's got more than one meaning. "Act up" can also mean "misbehave", as in. My children have been really acting up today. And if you say, "My boss is acting up." It could have either meaning. |
