Pay is usually expressed on a monthly basis. Remember that in regular employment in Portugal, you are paid for 14 months per year (i.e. including holiday pay and Christmas bonuses, usually paid in May/June and November/ December respectively), although this is presently taking other forms following exceptional measures by the government. If you are recruited by a multinational company, pay may be negotiated as an annual package, including subsidies and other fringe benefits.
Annual productivity bonuses are not common, although there may be scope for a bonus payment at the end of the year depending on profits. Only in medium-sized to large companies, mostly multinationals, are annual bonuses well integrated in remuneration policies.
Other benefits might be: improved health insurance cover or medical services, in the case of larger companies; and a mobile phone and company car, mostly for senior staff (managers and directors), although this practice is declining.
